WILLIAM G. BILLERMAN, F NEWARK, NEW JERSEY TOP FOB PEBCOLATORS Application filed February 12, 1930. Serial No. 427,685.

This invention relates to an improved top for percolators. These tops consist of a perforated lid and a glass dome that includes a flange extending through the perforation in the lid. The dome has a pair of small rounded projections on the outer face of the flange and the lid has recesses in the edge of the perforation. The dome is seated by passing the perforations through the recesses and then turning the dome. The thin metal of the lid becomes distorted and the dome soon fits too loosely to confine liquid in many cases causing leakage during percolation and loose enough to turn readily and to drop out when the coffee pot is tilted to pour out the contents.

The object of the invention is to provide a simple and cheap device for holding the dome against any turning except a forced turning and to hold the dome firmly and securely in place. The device is a spring wire clip to be snapped over one or both of the projections on the flange of the dome and to be seated between these perforations and the lower face of the lid at the edge of the hole through which the dome extends. The spring clip thus securely holds the dome in place but allows the removal thereof when it is broken and is to be replaced by a new one.

The spring wire clip can be formed in various ways but to make it possible to bend dome and clip together I prefer to make the clip in the form of a bail which has its end turned inwardly to fit into holes in the sides of the flange of dome and usually at points diametrically opposed to aline passing through the projections, in other words, the

on which the bail swings is perpendicular to the projections.

The accompanying drawings illustrate a device embodying my invention.- Figure 1 is a central section of a top for percolators showing improved securing means and Figure 2 is a bottom view of the top shown in Figure 1.

In the drawing'I show a conventional lid 10 and a conventional glass dome 11.. The dome 11 has an annular flange 12 which extends down through the hole or perforation 13 in the centre of the lid.

The flange 12 of the dome 11 has small rounded projec the edge of the der to allow tions 14 at opposite sides and hole 13 has recesses 15 in or the projections 14 to pass through. When the parts are assembled a spring w1re clip is snapped over the proection or pro jections 14 and thus seated by its spring action close up to the lower face of the lid at the edge of hole 13.

In order to keep the clip and dome together for sales purposes or to handle them as one article, the clip is detachably secured I to the dome.

To do this the flange 13 has holes or recesses 16 at right angles to the projections 14 form of a bail 1 inwardly and as a hinge for and the spring clip is in the 7 which has its ends 18 turned I seated in the holes 16 to act the bail. The wire is light enough to allow the ends to be spread apart to remove or install the bail in the dome and the bail, when in place, can be snapped over a projection 14 and seated between the proection and the bottom face of the lid.

I claim 1. A top for forated lid, a

percolators comprising a perdome restlng on the edges and with ends turned inwardly and extending into the holes.

2. In a top for percolators, a dome having an annular flange at its bottom, the flange having opposed holes on its outer face and a spring wire bail with its ends turned inwardly to extend into the holes.

In testimony whereof I affix my signature. WM. G. BILLERMAN.
